## What it is
An Objective-C library that adds motion blur effects to iOS UIView animations, primarily for position changes. It works by snapshotting the view and applying a custom Core Image blur kernel before the animation runs.

## Use cases
- add motion blur to iOS view animations
- make sliding menus look more life-like
- apply blur effect to fast-moving UI elements
- create custom blur effects with Core Image kernels on iOS
- polish spring animations with motion blur

## When to choose
- you want a motion blur effect on animating views in an iOS 8+ app
- you need a lightweight CocoaPods drop-in for UIKit animation polish

## When to avoid
- you need actively maintained or Swift-native code
- you need blur on properties other than position
- you target modern iOS where newer effect APIs are preferable

## Facets
- artifact type: library
- maturity: abandoned
- function: animation, image-processing, ui-components
- domain: mobile-development, graphics, frontend
- platform: cpp
- tags: objective-c, uikit, core-image, motion-blur, cocoapods, view-animations, ios, swift
